Well some parts I would say to practice in terms of pronunciation, of the ones that stuck out, would be the TH sound and the P at the end of slip (the punch sound of it). I'm currently teaching English in asia and they have similar problems with words like that, as well of Fs. I'm sure it'll be hard to improve pronunciation, but I'm sure you can manage! Not trying to seem harsh, just trying to help you out ! Good luck! Also, one of my favorite bands (before he made twin forks).
